I have three problems with this programmer.
-
With the programmer connected to the breadboard, it holds the avr in reset. e.g. On my reset line before the resistor I have 5V after the 10k resistor I have 0v. This tells me that something is drawing the reset pin low. The there’s no switch on my reset line, so it must be the programmer.
-
When the switch on the programmer is in the no power position, the programmer is still sending power to the board. e.g. My power indicator led lights up as do some of the pins on the avr (although not in the way the software i’ve programmed on the avr should tell them to light.) I expect the board to be dead when the no power switch is on.
-
The programmer seems to leave the avr in a state where it will only work imediately after being programmed. e.g. Cut the power, disconnect the programmer and turn power on again and the avr is dead, even though I’ve check Vcc and AVcc going into the avr as well as the reset line. Plug the programmer back in, reprogram and the avr software runs and my board performs as expected. Cut the power and turn power back on and the board is dead again.
